CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 474,123, dated May 3,1892.

Application filed January 16 1892. $eria1No. 418,276. (No model.)

To all whom it may concern:

Be it known that 1, DAVID URBANE GRAVE- LINE, a citizen of the UnitedStates, residing at Granby, in the county of Shefford and Province ofQuebec, Canada, have invented a new and useful Oar-Coupling, of whichthe following is a specification.

The invention relates to improvements in car-couplings.

The object of the present invention is to simplify and improve theconstruction of hookand-link car-couplings and to provide one which willcouple automatically and which may be readily uncoupled from the side ofthe car or the top thereof.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a portion of a carprovided with a car-coupling constructed in accordance with thisinvention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a reverseplan view. Fig. 4 is a side elevation of the draw-head.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates a hollow draw-head, which is supported beneath a car-body2, and within which on a transverse pin 3 is journaled a draw-hook 4,having its hook proper standing just in rear of the mouth 5 of thedrawhead 1. On the said transverse pin 3 is also journaled adraw-hook-lifting yoke 6, having its ends arranged at the sides of thehollow draw-head. The side bars 7 of the yoke 6 converge and meet andextend forward under the draw-head and vertically through a longitudinalslot 8 in the same and form an L-shaped portion 9, the upper end 10 ofwhich is bent horizontally and is arranged beneath the hook and supportsthe same when the latter is raised for uncoupling. The transverse pin orpivot 3 passes through the sides of the draw-head, eyes 11 of the yoke,and the pivothole 12 of thehook.

A rock-shaft 13 is journaled in suitable bearings across the end of thecar-body and having operating-handles 14: at its extremity arranged atthe sides of the car and provided at its center with an angularcrank-loop 15, which extends forward and which is arranged to meet theyoke to lift the same and raise the draw-hook. The draw-hook is raisedfrom the top of the car by a vertical rod 16, provided at its top with ahand-loop 17 and having at its bottom an arched portion 18, whichstraddles the draw-head, and which is provided at its ends'with eyes 19to receive the transverse portion of the rectangular crankloop, wherebythe rod 16 is attached to the same. The top of the rod 16 is arranged ina key-hole slot 20 of the projecting portion of the top of the car, andthe end 21 of the rod is extended along the latter for a short distanceto provide a stop which is adapted to engage the top of the car to holdthe hook elevated when the'rod 16 is lifted and moved in the narrowportion of the key-hole slot.

The coupling may be used in connection with either a straight link or acrooked one.

The draw-head is provided in its bottom near its rear end with anopening 22,in which the rear end of the hook is arranged and throughwhich the hook is inserted and removed, and the sides of the draw-headare enlarged at 23 on opposite sides of the openin g 22. Should thedraw-hook become broken it may be removed and a new one may be insertedwithout necessitating the removal of the draw-head.

What I claim is- 1. In a car-coupling, a hollow draw-head having an openmouth and provided in its bottom with a slot arranged near the front endand having an opening near its rear end, a transverse pivot passingthrough the sides of the draw-head, a hook arranged in the draw-head andhaving its rear end mounted on said pivot, a yoke having its sidesarranged on the sides of the draw-head and provided with eyes receivingsaid pivot, said yoke having an L-shaped portion arranged on the bottomof the draw-head and extending vertically through the said slot andsupporting the hook, and a rock-shaft provided with a crank-looparranged beneath the yoke and adapted to lift the same, substantially asdescribed.

2. In a car-coupling, a hollow draw-head provided in its bottom with aslot and with an with an arched portion straddling the drawhead andconnected to the crank-loop, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.
